My Q5 3,0 TDI from 2009 is giving me trouble when i am stopping and the gearbox goes from 2 to 1 gear (automatic gearbox) it is jumping to 1 gear and it feels like a big chok and like it is not a great feeling, i have reset the gearbox and it runs ok for 50 km and then it starts again ?? any ideas ? i have also changed the oil without any changes... The last update is also put in to the car. Hope anyone can help.
